On the basis of alleged obscenity, United States Customs officials seize 520 copies of Allen Ginsberg’s poem “Howl” that had been shipped from a London printer. The poem contained mention of illegal drugs and explicitly referred to sexual practices. A subsequent obscenity trial was brought against Lawrence Ferlinghetti, who ran City Lights Bookstore, the poem’s domestic publisher. Nine literary experts testified on the poem’s behalf, and Ferlinghetti won the case when a judge decided that the poem was of redeeming social importance.
